  1. Characteristics and Origins of Ridges and Troughs on the Top of the Middle Miocene Strata in the Beijiao Sag of the Qiongdongnan Basin, Northern South China Sea.Yufeng Li, Renhai Pu, Gongcheng Zhang & Hongjun Qu - 2021 - Interpretation 9 (2):SB1-SB15.
    Sedimentary structures generated by bottom currents are of interest to geologists. Based on the root mean square, coherence attribute, and 3D representations, ridges and troughs are imaged for the first time using 3D high-resolution seismic data and confirmed by a well, YL19-1-1, in the Beijiao Sag of the Qiongdongnan Basin. Combined with 2D seismic profiles, we define the flow direction of bottom currents resulting in ridges and troughs. The results indicate that ridges and troughs occur on the top of the (...)

    Seismic Interpretation of the Diapiric Structures and Gas Chimneys in the Liwan Gas Field, Pearl River Mouth Basin, Northern South China Sea.Xiaochuan Wu, Renhai Pu, Gongcheng Zhang, Xiaowei Fan, Dong Deng & Bin Li - 2018 - Interpretation: SEG 6 (3):T499-T519.
    Voluminous diapiric intrusions are present in 3D seismic data from the Liwan gas field area in the Baiyun sag of the Pearl River Mouth Basin, South China Sea. These diapirs are subdivided into magmatic diapirs and mud diapirs according to their seismic signatures and formation mechanisms. Saucer- and mound-shaped reflectors with anomalously high amplitudes distributed throughout the Early Miocene strata are interpreted as sills and laccoliths and are typified as magmatic diapirs. Mud diapirs in the study area can be divided (...)

    Controls on Abnormally High Porosity in a Deep Burial Reservoir of the Lingshui Formation in the Qiongdongnan Basin, South China Sea.Guangxu Bi, Chengfu Lyu, Qianshan Zhou, Guojun Chen, Chao Li, Gongcheng Zhang, Yilin Zhao & Chengze Li - 2020 - Interpretation 8 (3):SM53-SM64.
    Based on information including porosity and permeability, petrography, the stable isotopic composition of carbonate cements, and homogenization temperatures of aqueous fluid inclusions, we have studied the main factors for the development of abnormally high porosity in the Lingshui Formation reservoir of the Yacheng area. We found the sandstones were mainly subarkose, arkose, and lithic arkose and were texturally and compositionally immature. The research suggested that the sandstones existing close beneath the regional unconformity were formed during the Late Oligocene. Early diagenetic (...)

    Determining 3D Seismic Characteristics of the Conduit System of the Changchang Sag, Qiongdongnan Basin.Yufeng Li, Renhai Pu, Gongcheng Zhang, Qiang Han, Chao Yuan & Xueqin Zhao - 2021 - Interpretation 9 (2):T283-T297.
    Although some giant gas fields found in the deepwater area of the Qiongdongnan Basin, China, are often associated with mud diapirs and/or gas chimneys, no comprehensive 3D work has been undertaken to characterize them. We have conducted a 3D seismic investigation using the root-mean square, coherence, and instantaneous frequency attributes to provide a better understanding of the conduit systems in the QDNB. The results show that the conduit system that we investigated can be separated vertically into four zones in the (...)

    Determining 3d Seismic Characteristics of Conduit System of Changchang Sag, Qiongdongnan Basin.Yufeng Li, Renhai Pu, Gongcheng Zhang, Qiang Han, Chao Yuan & Xueqin Zhao - forthcoming - Interpretation:1-50.
    Although some giant gas fields found in the deep-water area of the Qingdongnan Basin, China, are often associated with mud diapirs and/or gas chimneys, no comprehensive 3D work has been undertaken to characterize them. We conducted 3D seismic investigation using root mean squares, coherence, and instantaneous frequency attributes to provide better understanding of the conduit systems in the Qiongdongnan Basin. The results show that the conduit system that we investigated can be separated vertically into four zones in the following order. (...)
